I own both consoles. Both have some good exclusive games, but in terms of reliability, if your friend wants a reliable console he should choose a PS3. The XBox does have a stronger line of games I'll admit.
As for other suggestions, if your friend likes FPS games I suggest he trys out Resistance 2 and Killzone 2. As for something scary, I strongly recommend Silent Hill Homecoming and Dead Space.
